论文摘要
我们介绍了对BCS平均场方案中二维单波性手性P波超导体的应变调节作用的研究。我们采用晶格模型，并通过数值求解相应的Bogolyubov-DE Gennes方程。假设菌株调制仅修饰跳跃幅度，我们观察到局部自发超电流的出现归因于系统的非平凡带拓扑。我们还报告说，应变调制可以诱导单个系统中拓扑上不同域的形成，该系统由光谱函数和局部Chern标记捕获。
We present a study of strain modulation effects on electronic structures of a two-dimensional single-band chiral p-wave superconductor within the BCS mean-field scheme. We employ a lattice model and numerically solve the corresponding Bogolyubov-de Gennes equations. Assuming that strain modulation only modifies hopping amplitudes, we observe the emergence of local spontaneous supercurrents that are attributed to the non-trivial band topology of the system. We also report that strain modulation could induce the formation of topologically distinct domains within a single system, which is captured by spectral functions and local Chern markers.
